Study on EUR method for tight gas fractured Wells in Sudongnan Block of Sulige Gas Field
The Estimated Ultimate Reserve(EUR)evaluation is an important work in the dynamic a-nalysis of tight oil and gas reservoirs.It is of great significance for reasonable work system,well pattern arrangement and adjustment.Based on the applicability analysis of the existing EUR evaluation methods,three EUR evaluation methods are recommended for fractured wells in tight sandstone gas reservoir.The applicability of different methods in different production stages of gas well is analyzed based on a case well in southeast Jiangsu Province.The results show that present production decline method is recommended in early production,present production decline method and material balance method are recommended in middle production,present production decline method and traditional production decline method are rec-ommended in later period of production.
